Intense pulsed light

Intense Pulsed Light (IPL), most commonly employed by medical practitioners and aestheticians working under the guidance of a physician, is a method of hair removal from the body. It involves the use of a specially constructed xenon flash lamp and focusing optics.

The Intense Pulsed Light hair removal process has become very popular due to its cheaper and faster procedure compared to laser hair removal. The comparison of effectiveness between Intense Pulsed Light and Laser Epilation is debated by scientists, equipment manufacturers and practitioners, but results are generally accepted to be roughly equivalent. IPL is generally advertised as "permanent hair reduction" as opposed to "permanent hair removal" (these phrases are misnomers when applied to laser or IPL hair removal). It is also used for the treatment of the skin in a process known as photorejuvenation.

Hair removal mechanics

The focused, broad-spectrumlight is applied to the surface of the skin by way of either a hand-held wand or an articulated arm. This light travels through the skin until it strikes the hair shafts or the bulb (root) of the hair. The bulb is usually where the highest concentration of melanin is located, as opposed to the rest of the hair shaft. As the light is converted to heat energy, the bulb and most of the hair shaft are instantly vaporized. The intense heat radiated by the hair also destroys the hair-producing Papilla or the entire hair follicle. It is also claimed that direct light-heat conversion occurs directly in the darker colored capillaries that bring nourishing blood to the follicle.

IPL technology is also employed in the treatment of medical disorders of the skin including:

In terms of rosacea, IPL offers one of the few effective treatments to relieve the facial redness associated with the disorder. Such treatment is best administered by a specialist dermatologist. This new technology incorporates 'dual mode filtering' and other important advances which result in safer and more effective treatment than older systems designed for hair removal.

The pulses of light produced by IPL equipment are very short in duration, so discomfort and damage to non-target tissues is minor. Most people who undergo IPL epilation only experience slight irritation similar to that of a minor sunburn though under certain circumstances, blisters may occur. Men undergoing the procedure experience greater discomfort as male body hair is generally thicker than women's. Depending on the instrument settings and intensity, treating sensitive areas such as the chest and face can result in pain comparable to waxing the same areas; however this pain dissipates immediately. The light that emanates from the IPL wand is filtered to remove any ultraviolet components, eliminating the possibility of UV skin damage.
